Receive notification of basic DTD-related events
Receive notification of basic DTD-related events.If a SAX application needs information about notations and unparsed entities, then the application implements this interface and registers an instance with the SAX parser using the parser's setDTDHandler method. The parser uses the instance to report notation and unparsed entity declarations to the application.
The SAX parser may report these events in any order, regardless of the order in which the notations and unparsed entities were declared; however, all DTD events must be reported after the document handler's startDocument event, and before the first startElement event.
It is up to the application to store the information for future use (perhaps in a hash table or object tree). If the application encounters attributes of type "NOTATION", "ENTITY", or "ENTITIES", it can use the information that it obtained through this interface to find the entity and/or notation corresponding with the attribute value.
The HandlerBase class provides a default implementation of this interface, which simply ignores the events.
It is up to the application to record the notation for later reference, if necessary.
If a system identifier is present, and it is a URL, the SAX parser must resolve it fully before passing it to the application.
Note that the notation name corresponds to a notation
reported by the notationDecl() event. It is up to the
application to record the entity for later reference, if
necessary. If the system identifier is a URL, the parser must resolve it
fully before passing it to the application.
This method helps in reseting the DTD object implementational
defaults each time the DTD is begun. virtual void unparsedEntityDecl( const XMLCh* const name, const XMLCh* const publicId, const XMLCh* const systemId, const XMLCh* const notationName )
publicId - The entity's public identifier, or null if none
was given.
systemId - The entity's system identifier (it must always
have one).
notation - name The name of the associated notation.
